Major depressive disorder (MDD) is associated with disruptions in glutamatergic and GABAergic activity in the medial prefrontal cortex (mPFC), leading to altered synaptic formation and function. Low doses of ketamine rapidly rescue these deficits, inducing fast and sustained antidepressant effects. While it is suggested that ketamine produces a rapid glutamatergic enhancement in the mPFC, the...

Electroconvulsive therapy (ECT) is recognized as one of the most efficacious interventions for depression. However, it is associated with impairments in learning and memory functions. Ketamine has demonstrated potential in mitigating cognitive deficits. Notably, the metabotropic glutamate system is hypothesized to play a pivotal role in cognitive process regulation. Nevertheless, the...

Ketamine is a racemic compound and medication comprised of (S)-ketamine and (R)-ketamine enantiomers and its metabolites. It has been used for decades as a dissociative anesthetic, analgesic, and recreational drug. More recently, ketamine, its enantiomers, and its metabolites have been used or are being investigated for the treatment of refractory depression, as well as for comorbid disorders...

3,4-methylenedioxymethamphetamine (MDMA; commonly referred to as "ecstasy" or "molly") is a substituted amphetamine drug that is used recreationally for its acute psychoactive effects, including euphoria and increased energy, as well as prosocial effects such as increased empathy and feelings of closeness with others. Acute adverse effects can include hyperthermia, dehydration, bruxism, and...

Novel antidepressive substances are challenging the explanations for the mechanisms of action of traditional psychopharmacology. What could be the shared effects of various antidepressants and in this context what role do extrapharmacological factors, such as the body and environment, play? The available literature on clinical and preclinical data for assumed combined active factors of...

Since its synthesis in 1962, ketamine has been widely used in diverse medical contexts, from anesthesia to treatment-resistant depression. However, interpretations of ketamine's subjective effects remain polarized. Biomedical frameworks typically construe the drug's experiential effects as dissociative or psychotomimetic, while psychedelic paradigms emphasize the potential therapeutic merits of...

While ketamine, an NMDA receptor antagonist, is effective in treating major depression, studies have not addressed the safety of repeated ketamine infusions in depressed patients with comorbid alcohol use disorder (AUD). In this study, we aimed to determine whether a history of chronic social isolation and alcohol exposure alter the reinforcing properties of ketamine in male and female rats....

Persons with schizophrenia are excluded from psychedelic-assisted therapy due to concerns about the risk of triggering or worsening psychosis. However, there is limited meta-analytic data on the risk of psychedelic-induced psychosis in individuals with pre-existing psychotic disorders. We conducted a systematic review, meta-analysis, and overview of reviews to assess the incidence of...

Preliminary evidence suggests that psychedelic-assisted therapy-the enhancement of psychotherapy with psychedelics such as 3,4-methylenedioxymethamphet-amine (MDMA) and psilocybin-may be efficacious for depression, posttraumatic stress disorder, substance use disorders, and other conditions. Therapeutic psychedelic research is advancing steadily, with psilocybin, MDMA, and lysergic acid...

ABSTRACT Purpose To evaluate the current level of evidence for the use of psychedelics for the management of cancer pain and associated psychological distress. Content Pain is a common symptom of cancer and treatment. However, there are high rates of undertreatment of cancer pain due to the complex underlying biology of the condition, and potentially due to a decrease in opioid prescribing in...
